Transformers: Age of Extinction

The fourth instalment of Michael Bay’s big screen robot romp offers few surprises but an abundance of the series’ familiar tropes in another marathon-length, narratively vapid action spectacular. Bay’s trademark visual fireworks are as impressive as ever, while an all-new cast promises a new direction for what may become a second trilogy. Otherwise, it’s business as usual for the Autobots and Decepticons, which based on past performance means huge box office everywhere.
